# group `midi_device` {#group__midi__device}
|
|
|
|
You use the functions when you are implementing your own midi device.
|
|
|
|
You set a send function to actually send bytes via your device, this method is called when you call a send function with this device, for instance midi_send_cc
|
|
|
|
You use the midi_device_input to process input data from the device and pass it through the device's associated callbacks.
|
|
|
|
You use the midi_device_set_pre_input_process_func if you want to have a function called at the beginning of the device's process function, generally to poll for input and pass that into midi_device_input

Process input bytes. This function parses bytes and calls the appropriate callbacks associated with the given device. You use this function if you are creating a custom device and you want to have midi input.
|
|
|
|
#### Parameters
|
|
* `device` the midi device to associate the input with
|
|
|
|
* `cnt` the number of bytes you are processing
|
|
|
|
* `input` the bytes to process
|
|
|
|
#### `public void `[`midi_device_set_send_func`](#group__midi__device_1ga59f5a46bdd4452f186cc73d9e96d4673)`(`[`MidiDevice`](#struct__midi__device)` * device,midi_var_byte_func_t send_func)` {#group__midi__device_1ga59f5a46bdd4452f186cc73d9e96d4673}
|
|
|
|
Set the callback function that will be used for sending output data bytes. This is only used if you're creating a custom device. You'll most likely want the callback function to disable interrupts so that you can call the various midi send functions without worrying about locking.
|
|
|
|
#### Parameters
|
|
* `device` the midi device to associate this callback with
|
|
|
|
* `send_func` the callback function that will do the sending
|
|
|
|
#### `public void `[`midi_device_set_pre_input_process_func`](#group__midi__device_1ga4de0841b87c04fc23cb56b6451f33b69)`(`[`MidiDevice`](#struct__midi__device)` * device,midi_no_byte_func_t pre_process_func)` {#group__midi__device_1ga4de0841b87c04fc23cb56b6451f33b69}
|
|
|
|
Set a callback which is called at the beginning of the midi_device_process call. This can be used to poll for input data and send the data through the midi_device_input function. You'll probably only use this if you're creating a custom device.
|
|
|
|
#### Parameters
|
|
* `device` the midi device to associate this callback with
|
|
|
|
* `midi_no_byte_func_t` the actual callback function
|
|

# struct `_midi_device` {#struct__midi__device}
|
|
|
|
This structure represents the input and output functions and processing data for a midi device.
|
|
|
|
A device can represent an actual physical device [serial port, usb port] or something virtual. You should not need to modify this structure directly.
